CVE-2024-3568: Huggingface Transformers

Critical severity, CVSS 9.6. EPSS: 2.1% chance of exploitation in the next 30 days.

The huggingface/transformers library is vulnerable to arbitrary code execution through deserialization of untrusted data within the `load_repo_checkpoint()` function of the `TFPreTrainedModel()` class. Attackers can execute arbitrary code and commands by crafting a malicious serialized payload, exploiting the use of `pickle.load()` on data from potentially untrusted sources. This vulnerability allows for remote code execution (RCE) by deceiving victims into loading a seemingly harmless checkpoint during a normal training process, thereby enabling attackers to execute arbitrary code on the targeted machine.

Affected products

• Huggingface Transformers: before 4.38.0 (fixed in 4.38.0)
